Recently, Steam was updated with engine enhancements that were added primarily for DOD: Source. Along with these enhancements came the addition of the 7.2 .vtf file format, which is used in a handful of DOD: Source textures. The 7.2 .vtf file format adds support for volumetric textures that, to my knowledge, are only used internally by the engine at this time. The SDK has not been updated.

VTFLib v1.2.0 adds support for the 7.2 .vtf file format and fixes the RGBA16161616F encoder and decoder (this is a HDR format and up until now it wasn't clear how it was being represented). I strongly recommend that users update to the new versions of VTFLib and VTF Plug-In as the previous versions may corrupt 7.2 textures. Note: the volumetric textures have not been tested as I have been unable to get a sample from Valve. So lets just pray it all works... I will try to update VTFEdit with improved HDR texturing capabilities in the future, but right now I am simply too busy.
